Influence of Arsenic speciation during the adsorption on different materials

摘要

One of the most toxic and dangerous compounds of wastewatcr is arsenic. Removal of arsenic from aqueous solution has been achieved with different adsorbents based on aluminum, lanthanum, clay minerals etc. Many studies have been also carried out with various resins including exchange resins and Fe (Ⅲ) - loaded chelating resins. In this paper, a study on iron (Ⅲ) loaded iminodiacetate resin and nanocomposite materials is presented. The influence of pH on (Ⅴ) and (Ⅲ) arsenic adsorption has been determinated. The kinetics of the adsorption process has been also investigated.
